Hairpins, of Which theafollowing is a speci Thisinvention relates' to. hair pins so Constructed as to cause them to turn through angles of 90 degrees While being 'inserted in place, thereby securely locking them in the The objects of the invention are to provide a hair pin which can be readily and inexpensively produced, which can be easily placed in the hair, and so constructed that by means of certain bends in its prongs that upon engagement of the bends with the hair While being inserted therein, the pin Will turn upon itself through angles Of 90 degrees, thereby causing the hair to be wrapped in or upon the pin Which holds the pin in Permanent position.

Referring to the drawings in which the same character indicates the same part in the several views:

Fig. 1 is a front elevation of a hair pin' cmbodying my invention.

Fig. 2 is a side elevation of the same.

F ig; 3 is a section on line 3-3 of Fig. 2.

Fig. 4 is a section on line 4--4 of F ig. 2.

Fig. 5 is' a grouped illustration of the positions of the hair pin while it is being inserted in the hair.

Fig. 6 is a, frontelev'ation of a modified form of my invention.

Fig. 7 is a side elevation of the same.

Fig. 8 is a grouped illustration of the, portion of the hair pin of Figs. 6 'and 7 while being inserted into the hair.

Referring to Figs. 1 to 5, the hair pin consists of tWO le s Or prongs 11 and 12 connected by a bridge portion 10. Substantially midway of the prong 11 is an angular bend consisting of two portions 13 and 14 meeting at an apex 15, the portion 13 being bent up from the leg 11 at 16, and the portion 14 being bent from the leg 11 at 17.

In the leg or prong 12 is a similar bend consisting of portions 23 and 24 meeting at an apex 25, the portion 23 being bent at 26 and the portion 24 being bent at 27. .The said bends in the prongs 11 and 12 respectively lie in planes at right angles to each other, the apex 25 of the bend in'the prong 12, being situated immediately.: underneath the. apexzl of the: bend in theprong 11.

When the hairpingof Figs. 1 and 2 is inserted into thenhair by lpressure, at 0,' the pin, .because of theengagement of the 'bends with the hair, willgbe-forced' toat-urn through an. angle of QOdegrees andthen upon fur ther insertion the -pin will turn back. again v through an angle of 90 degrees, there/by en;

gaging or wrapping the hair about the pin, causing the pin to be firmly secured into the hair of the Wearer. The first 90 de 'rees turnis indicated by the arrow and the following 90 degrees in-a reverse direction'- is indicated by the arrow Figs. 6 and 7 illustrate a modified structure in whichthe prongs 31 and 32 are connected by a bridge 30. Each of the prongs is provided with a series of duplicate bends, the bends of each prong lying respectively in planes at right angles to each other. The

apic-es of the two end bends in one prong lie directly underneath the apices of the two end bends in the other prong, whereas the apex of the central bend of the last mentoned prong lies underneath the apex of* the central bend of the first mentioned prong. 4 f

The bends in the' prong'31'are formed by the portions 33, 34, 35 and 36, forming apices 37, 38 and 39,' whereas the bends in the prong 32 are formed by the portions 33, 34'. 35' and 36' forming apices 37 38' and 39'.

As illustrated in Fig. 8, when the hair pin is forced into the hair by 'pressure at the point C, the pin Will first turn throu h 90 degrees, shown at the arrow y, and Wil turn back through 90 degrees as at the arroW y' and again reverse itself and turn through an angle ,of 90 degrees at y and again re.- verse itself and turn through an angle of 90 degrees, as indicated by the arrow y thus effectually looking the hair pin into the hair.

The hair pin may be made of Wire or of any other suitable material 'such as bone, Shell or composite.

Having thus described my invention What I claim as new and desire to secure by Letters Patent is:

1. A hair pin comprising a Wire bent to form a brid e portion and a pair 'of leg portions extending therefrom, each leg portion having an an ular bend in a plane at an angle to the ane of the bend of the other leg portion, he apex of One of said angular bends touching the plane of the other .bend

below the apex of said end.

2. A hair pin comprising a. wirebent to form a bridge portion and a pair of leg 'portions extending therefrom in a common' plane, one leg portion having an angular bend in a plane at a, right angle to said Common plane of said leg portions and the other leg portion'having an angular bend in the plane of said leg ort-ions', the apex of said bend touching the median of the bend of the other leg portion.

po rtion, the apices of the bends of one of said leg portions touching the plane of the bends of the other leg portion On substan tially median lines from the apices of the respective angles of said bends.

4. A hair pin comprising a Wire bent to form a bridge portion and a pair of leg portions, said leg portions having straight portions lying in a, common plane, One of said leg portions having bends In a plane at ri ht angles to said common: plane of said eg portions and 'the other leg portion having bends in said common plane positioned with their apices on the median line of the apices of the bends of the other leg portion;
